Token approvals

An approval lets an app move a token from your wallet, up to an amount you allowed.

What it means

Unlimited approvals stay active until you revoke them, so a hacked or fake app can still move those tokens later.

What to watch

Unlimited allowances, approvals for apps you no longer use, and approval requests from sites you don't know.

How Compass-Alpha uses it

Wallet token lists flag suspicious tokens with a warning: don't swap them or sign anything for them.
